ROTARY BRICK-MACHINE.

Specification of Letters Patent No. 15,005, dated June 3, 1856.

To all whom it may concern Be it known that I, GEORGE CRANGLE, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Rotary Brick-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1, is a perspective view of a double cylinder rotary brick machine with the improvement applied; and Fig. 2, a sectional side view of the upper part of the same like letters, when on both the figures indicating the same objects.

The nature of my invention consists in a peculiar apparatus applied to a rotary double cylinder brick machine for the purpose of more effectually causing the cylinders which contain the molds, to rotate and stop alternately and regularly so as to bring each mold successively directly under its plunger immediately before it comes in contact therewith.

Referring to the drawings-A is the frame; B, B, the cylinders containing the mold (b, b) C, the actuating shaft, having reversed cranks (c, 0,) carrying the plungers so as to cause the one to ascend as the other descends, in a well known manner.

D, is the pulley for driving the machine; E, the pulley for actuating the off bearing bands (F, F,) on the pulleys G, G. The plungers are arranged so as to slide up and down by the action of the cranks, in guides fixed to the frame in a well known manner, and regulated by a balance wheel; not shown in the drawingsthe molds in the cylinders being arranged around their peripheries so that the spaces between each mold of one cylinder shall be exactly opposite to the mold in the otl1erand both cylinders firmly fixed upon the one horizontal carrying and sustaining shaft H.

The apparatus for moving and stopping the cylinders as described, consists of the disk (I) fixed on the outer end of the actuating shaft (C) and having four radiating arms with friction rollers in the endstwo of which arms (K, K) are fixed on the inner side of the disk and so as to project in opposite directions; and the other two (L, L,) on the outer side in the same manner though at right angles to the others, as shown in the drawings. Near the middle of the frame (A) a horizontal and nearly equal armed lever (M) has its fulcrum-pin secured so as to permit the said lever to be vibrated through a short distance, by means of two upwardly projecting branches (N and 0), so arranged that the one (N), may be operated only by the radial arms (L L) and the other one (0), only by the radial arm K, K,-as will hereafter be described. Fixed to the under side of this lever (M) and near one end, is another branch (P) which projects downward so that it may be brought to engage in the notches of the outer one of two ratchet wheels (Q, and R) which are fixed on the projecting end of the cylinder shaft The other end of this lever (M) has a friction roller (S) which is adapted to allow the end of said lever to move back and forth between and in contact (by the roller) with the two fiat projections on the vertical end of an L lever (T) which has its horizontal end loosely fixed to the shaft (H) of the cylinders (B B), at any suitable place thereon between the frame (A) and the ratchet wheels. Near the angle of the bent lever (T) a pawl (U) and spring (V) are attached, so that the pawl, and ratchet (B), may be kept in contact with each other in the usual manner. The lever (T) rests upon the stationary sup port (W) beneath when not in contact with either of the radial arms on the disk As a security against any back-lash of the cylinders, a small spring catch (X) is fixed to the frame (A) so as to catch in a ratchet wheel, or in notches cut inthe cylinder at this part.

Operation: Clay being placed in the hoppers in the usual manner, and rotation given to the actuating shaft (C) in the direction of the arrow, one of the radial arms K) comes in contact with the branch (0) of the lever (M) and moves it outwardly, depressing that end of the lever (M), while its other end is thus caused to lift the lever (T), which being coupled to the ratchet (R) by means of the pawl (U), causes the cylinders to rotate until checked by the lower branch (P) of the lever (M) engaging with the ratchet One of the plungers now comes in contact with one of its molds and forms or presses the clay into a brick. The radial arm (K) having now passed the branch (0) of the lever (M), one of the radial arms (L) comes in contact with the branch (N) of the lever (M), depressing that end, lifting the branch P, out of the notch in the ratchet (Q), and drawing back the pawl (U) into the next notch, while the plunger which has just pressed the clay into a brick, rising and the invention consist as before mentioned in thefact that it effects a regular, accurate, certain and harmonious operation of the molds and plungers together; and consequently diminishes the wear and tear of the machine.

I do not claim a rotary, double cylinder brick machineas such machines have been used before; nor do I claim arranging the molds around the cylinders so as to alternate with two plungers on one actuating shaft; but

What I claim as my invention and desire to secure by Letters Patent, is,

The apparatus for rotating and stopping the cylinders of rotary brick machines, as described-the said apparatus consisting of the armed disk (I), the branched lever (M), the bent lever (T), pawl (U) and the ratchet wheel (Q and R)the same being constructed, arranged, combined and operating substantially in the manner, and for the purpose set forth and described.
